Usage
Review Local Changes (Default)
# Smart auto-detection (zero configuration)
/android-code-review
The plugin automatically detects what to review:
- Staged changes →
git diff --staged - Unstaged changes →
git diff - Last commit →
git log -1 --patch
In case you only want to review the stated files:
# Explicit staged changes
/android-code-review --target staged
Review Specific File
/android-code-review --target file:app/src/main/java/com/example/MyFragment.kt
Severity Filtering
# Security-only (fastest)
/android-code-review --severity critical
# High-severity (default)
/android-code-review --severity high
# All checks
/android-code-review --severity all
JSON Output (CI/CD)
android-code-review --output-format json > review.json
Pull Request Review
Review Specific PR
# Review a PR by number
/android-code-review --target pr:123
# High-severity only (faster)
/android-code-review --target pr:123 --severity high
# Export as JSON for archiving
/android-code-review --target pr:123 --output-format json > pr-123-review.json
Note: The default behavior reviews local git changes, not pull requests. Use --target pr:<number> for PR review.
